Oral calcium supplements (80 mg/kg per 24 h) were given to 23 preterm infants, and the course of serum calcium, magnesium, immunoreactive calcitonin, and gastrin was compared with a control group of 23 matched infants. In the supplemented group, serum calcium concentrations remained at the baseline level (2.31 mmol/l +/- 0.18 SD) while a fall (from 2.27 +/- 0.18 to 1.91 +/- 0.24 mmol/l) was observed at 12-16 hours of age in the control group, with 4 values , 1.75 mmol/l. There was no change in serum magnesium concentration in either group. The postnatal rise of serum immunoreactive calcitonin concentrations in the control group (from 171 +/- 135 to 493 +/- 273 pg/ml at 12-48 hours of age) was not found in the supplemented group. There was a negative correlation between serum calcium and immunoreactive calcitonin levels in the control group, but not in the supplemented group. There was no correlation between serum immunoreactive calcitonin and gastrin concentrations. These data show that oral ...

Biological activity of porcine calcitonin was most actively inactivated by the rat kidney homogenate than by other tissue homogenates. Among the various subcellular fractions of the rat kidney homogenate examined, microsome fraction was most active in the in vitro inactivation of porcine calcitonin. Inactivation of porcine calcitonin by the rat kidney microsome was dependent on pH and temperature. Inactivating activity of the rat kidney microsome was inhibited by 1 X 10(-3) M monoiodoacetate and 1 X10(-5) M p-chloromercuribenzoate. These results suggest that porcine calcitonin is probably inactivated by a SH-enzyme in the rat kidney microsomes. However, the participation of other enzymes cannot be ruled out, since the inactivating activity of the rat kidney microsome fraction is also inhibited by 1 X 10(-4) M diisopropylfuorophosphate. ...

Results There is no significant difference between two groups, in age, Sex, and symptoms. Serum and CSF procalcitonin, Leukocytosis ,15000, PMN peleocytosis of CSF and also sugarand protein of CSF were significantly higher in bacterial meningitis. Serum and CSF procalcitonin levels in control group were less than 0.5 ng/ml and ,2 ng/ml in bacterial meningitis and only one child (8.33%) in aseptic meningitis (Herpes meningoencephalitis) had serum procalcitonin more than 2 ng/ml same bacterial meningitis.. ...

Background: Anastomotic leaks in colorectal surgery results in a high morbidity and mortality rate. Serum procalcitonin levels is known as a sensitive and specific marker of sepsis and could be use as a marker for early detection of a leak allowing early intervention. It may help a clinician decide to perform a CT scan even earlier especially when the diagnosis of a leak is uncertain. The aim of this study is to determine whether serum procalcitonin is a good predictor of anastomotic leak in colorectal surgery. Methodology: Between July 2014 until October 2015, 70 patients undergoing colorectal surgery were prospectively analyzed in a single-center tertiary teaching hospital. Demographic and surgical data were obtained. Serum procalcitonin was taken before surgery and at day 3 (72 hours) postoperatively. During the postoperative period, the patients were observed in the ward for features of anastomotic leak and if present, it was managed accordingly. The primary outcome was to prospectively ...

Purpose: To correlate ultrasonographic (US) features of medullary thyroid carcinoma (MTC) with pre operative and postoperative calcitonin levels. Materials and Methods: A total of 130 thyroid nodules diagnosed as MTC were evaluated. Two radiologists retrospectively evaluated preoperative US features according to size, shape, margin, echogenicity, type of calcification, and lymph node status. Postoperative clinical and imaging followup (mean duration 31.9 22.5 months) was performed for detection of tumor recurrence. US features, presence of LN metastasis, and tumor recurrence were compared between MTC nodules with and without elevated preoperative calcitonin (|100 pg/mL). Those with normalized and nonnormalized postoperative calcitonin levels groups were also compared. Results: Common US features of MTCs were solid internal content (90.8%), irregular shape (44.6%), circumscribed margin (46.2%), and hypoechogenicity (56.2%). Comparing MTC nodules with and without elevated preoperative calcitonin levels,

Calcitonin is a circulating polypeptide that inhibits bone resorption by inducing both quiescence (Q effect) and retraction (R effect) in osteoclasts. Two structurally related members of the calcitonin gene peptide family, calcitonin gene-related peptide (CGRP) and amylin, inhibit osteoclastic bone resorption selectively via the Q effect. In the present study, we have made measurements of cell spread area in response to the application of amylin, CGRP and a peptide fragment of CGRP, CGRP-(Val8Phe37). We found that, over a wide concentration range (50 pmol/l to 2.5 mumol/l), the selective Q effect agonists did not produce an R effect. Furthermore, the peptides, when used at a 50-fold higher molar concentration than calcitonin, did not antagonize calcitonin-induced cell retraction. Additionally, experiments designed to measure changes in the intracellular free calcium concentration ([Ca2+]i) in single osteoclasts revealed that, unlike calcitonin, the non-calcitonin Q effect agonists did not produce a rise

Evaluation of: Riedel S, Melendez JH, An AT, Rosenbaum JE, Zenilman JM. Procalcitonin as a marker for the detection of bacteremia and sepsis in the emergency department. Am. J. Clin. Pathol. 135(2), 182-189 (2011). In a recent report, Riedel et al. proposed a procalcitonin cutoff of 0.1 ng/ml to rule out bacteremia in adult patients presenting to the emergency department with systemic infections. Procalcitonin levels were higher in patients with true bacteremia than in patients with negative blood cultures or bacteremia due to possible contaminants. For prediction of bacteremia, a procalcitonin level of 0.1 ng/ml had an excellent negative predictive value of 96.3%, and a good sensitivity of 75%, specificity of 70.6% and area under the curve of 0.73, but poor positive predictive value of 12.8%. Based on the results in this study, we propose that a procalcitonin value of 0.1 ng/ml or less could be used to rule out bacteremia (NPV: 96.3 ...

Cytokines, nitrite/nitrate, soluble tumor necrosis factor receptors, and procalcitonin concentrations : comparisons in patients with septic shock, cardiogenic shock, and bacterial pneumonia

The clinical utility of serum procalcitonin levels in guiding antibiotic treatment decisions in patients with sepsis remains unclear. This patient-level meta-analysis based on 11 randomized trials investigates the impact of procalcitonin-guided antibiotic therapy on mortality in intensive care unit (ICU) patients with infection, both overall and stratified according to sepsis definition, severity, and type of infection. For this meta-analysis focusing on procalcitonin-guided antibiotic management in critically ill patients with sepsis of any type, in February 2018 we updated the database of a previous individual patient data meta-analysis which was limited to patients with respiratory infections only. We used individual patient data from 11 trials that randomly assigned patients to receive antibiotics based on procalcitonin levels (the

Peptides , Calcitonin Related Peptides; Calcitonin gene-related peptide (CGRP), adrenomedullin (ADM) and amylin belong to a unique group of calcitonin-related peptide hormones important for homeostasis in diverse tissues. Calcitonin, a 32-amino acid peptide hormone, is essential for calcium balance, whereas CGRP and ADM are important for neurotransmission and cardiovascular and respiratory function. Calcitonin regulates mineral balance by controlling blood concentrations of calcium and phosphorus metabolism and can cause hypercalcemia. An increase in the serum calcium level is known to stimulate calcitonin secretion. In mammals, the major source of calcitonin is from the parafollicular or C cells in the thyroid gland, but it is also synthesized in a wide variety of other tissues, including the lung and intestinal tract. Calcitonin contains a single disulfide bond, which causes the amino terminus to assume the shape of a ring. The calcitonin family of peptides act through G-protein protein coupled

The rapid recognition of these 2 different conditions is important for their proper treatment. An elevated procalcitonin (PCT) level is commonly detected in patients with bacterial infections. This study assessed the usefulness of the serum PCT level as a biomarker for the differential diagnosis of acute ...

PCT is the prohormone of the hormone calcitonin, but PCT and calcitonin are distinct proteins. Calcitonin is exclusively produced by C-cells of the thyroid gland in response to hormonal stimuli, whereas PCT can be produced by several cell types and many organs in response to proinflammatory stimuli, in particular by bacterial products.1. In healthy people, plasma PCT concentrations are found to be below 0.1 μg/L.2 Depending on the clinical background, a PCT concentration above 0.1 μg/L can indicate clinically relevant bacterial infection, requiring antibiotic treatment.3 PCT levels rise rapidly (within 6 to 12 hours) after a bacterial infectious insult with systemic consequences. The magnitude of the increase in PCT concentration correlates with the severity of the bacterial infection.4 At a PCT concentration ,0.5 μg/L, a patient should be considered at risk of developing severe sepsis or septic shock.5,6 On the other hand, the relief of the septic infection is accompanied by a decrease in ...

Although, glucocorticoid (GC) and calcitonin-induced changes in bone repair have been studied previously, the exact effects of these on fracture healing remain controversial. Hence, the purpose of this experimental study is to determine biochemical and histological effects of locally administrated GC and systemically administrated calcitonin on the kinetics of healing response after bone marrow ablation in rats. After having undergone marrow ablation, a steroid-treated group of rats (n = 24) received a single dose of intramedullary methylprednisolone (2 mg/kg), a calcitonin-treated group (n = 24) received intermittently administrated subcutaneous salmon calcitonin (16 IU/kg), and a control group (n = 24) received intramedullary saline (25 μl). Blood samples taken on days 1, 3, 7, 9, and 15 after ablation showed an increase in serum calcium, alkaline phosphatase (ALP), and phosphate levels in the Calcitonin and Control groups. Levels of calcium and ALP peaked on day 7 after ablation. However, an

Of 80 MEN2A gene carriers (in 61 of whom carrier status was proved by DNA analysis), 66 had abnormal plasma calcitonin values and medullary thyroid carcinoma. Fourteen young carriers had normal results of plasma calcitonin tests. In 8 of these 14, thyroidectomy revealed small foci of medullary thyroid carcinoma; the remaining 6 have not yet been operated on. Of the other 220 family members, 68 were found by DNA analysis not to carry the MEN2A gene. None of these 68 subjects had medullary thyroid carcinoma or pheochromocytoma; 6 had elevated plasma calcitonin concentrations and underwent thyroidectomy but had only C-cell hyperplasia. Conclusions: ...

Fifteen eight-week-old female Sprague Dawley rats were used to determine the effects of thyrocalcitonin on osteogenic regeneration. Bone fragments of 2.8-5.3 mm were extracted from the mid-shaft of the right hind fibulae. Following surgery, seven control animals were administered saline for twenty consecutive days, whereas eight experimental animals were injected subcutaneously with 7.5 mMRC/200 g body wt of thyrocalcitonin for twenty consecutive days. After experimentation was complete, the rats were sacrificed and morphological observations were made to quantify the lengths of fibulae gaps before and after treatment. Statistical analysis indicates that bone regeneration occurs at a faster rate in those animals receiving thyrocalcitonin ...

Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis. It was first identified by Leonard J. Deftos and Bernard A. Roos in the 1970s. It is composed of 116 amino acids and is produced by parafollicular cells (C cells) of the thyroid and by the neuroendocrine cells of the lung and the intestine. The level of procalcitonin in the blood stream of healthy individuals is below the limit of detection (0.01 µg/L) of clinical assays. The level of procalcitonin rises in a response to a proinflammatory stimulus, especially of bacterial origin. It is therefore often classed as an acute phase reactant. In this case, it is produced mainly by the cells of the lung and the intestine.... It does not rise significantly with viral or non-infectious inflammations. With the derangements that a severe infection with an associated systemic response brings, the blood levels of procalcitonin may rise to 100 µg/L. In serum, procalcitonin has a ...

Background and Objective: Vitamin D is known to modulate thyroid neoplastic and autoimmune disease. We investigated the role of the vitamin D receptor (VDR) in normal thyroid development and function (thyrocytes and C cells). Methods: The thyroid phenotype of VDR knockout mice was studied in comparison to wild-type controls. The mice were fed a normal diet or a calcium-rich diet to circumvent effects induced by hypocalcemia. Results: Thyroid morphology was unaltered in VDR knockout mice. Also, expression of different parameters of thyrocyte function was comparable (immunohistochemistry). C cell physiology was, however, affected in the absence of the VDR, resulting in increased thyroidal calcitonin expression (immunohistochemistry), paralleled by increased serum calcitonin levels, but only in normocalcemic mice. To study a possible effect of vitamin D status on basal calcitonin levels in humans, serum calcitonin concentrations were compared between vitamin D-deficient and -sufficient patients ...

OBJECTIVE: To examine the relationship of early serum procalcitonin (PCT) levels with the severity of post-cardiac arrest syndrome (PCAS), long-term neurological recovery and the risk of early-onset infections in patients with coma after cardiac arrest (CA) treated with therapeutic hypothermia (TH).. METHODS: A prospective cohort of adult comatose CA patients treated with TH (33°C, for 24h) admitted to the medical/surgical intensive care unit, Lausanne University Hospital, was studied. Serum PCT was measured early after CA, at two time-points (days 1 and 2). The SOFA score was used to quantify the severity of PCAS. Diagnosis of early-onset infections (within the first 7 days of ICU stay) was made after review of clinical, radiological and microbiological data. Neurological recovery at 3 months was assessed with Cerebral Performance Categories (CPC), and was dichotomized as favorable (CPC 1-2) vs. unfavorable (CPC 3-5).. RESULTS: From December 2009 to April 2012, 100 patients (median age 64 ...

There appears to be a consensus that 100 IU/day of nasally administered salmon calcitonin may prevent trabecular bone loss during the first years of the menopause. Strong evidence exists that half that dose may also be sufficient to prevent trabecular bone loss and that higher doses (, or = 200 IU/day) induce a significant increase in spinal bone mineral content. Calcium supplements should be systemically administered when calcitonin is given, particularly at high doses. Rectal calcitonin seems also to be an efficient alternative in prevention of trabecular bone loss. Further studies are required to evaluate the effect of calcitonin in prevention of cortical bone loss. In established osteoporosis, calcitonin may prevent further bone loss ...

The novel inflammatory marker procalcitonin (PCT) was assessed as an index of infection in patients with febrile neutropenia. Blood samples were obtained from 115 patients with febrile neutropenia for determination of PCT levels before onset of fever and daily until the resolution of fever. The median PCT level on the first day of fever was 8.23 ng/mL in patients with bacteremia, compared with 0.86 ng/mL in patients with localized bacterial infections (P = .017). The median PCT level on the first day of fever was 2.62 ng/mL in patients with severe sepsis, compared with 0.57 ng/mL in patients with clinically localized infections (P , .001). A dramatic decrease in PCT levels was documented after resolution of the infection; PCT levels were elevated when the infection worsened. Pronounced PCT levels were also found in patients with fever of unknown origin who were responding to antimicrobial chemotherapy, compared with those not responding to treatment with antibiotics. PCT levels were particularly ...

In HAP, CAP and, to a lesser extent, AECB, but not TB, significantly elevated median PCT levels were found compared to controls. However, median PCT levels in all groups were below the recommended cut-off level of 0.5 ng·mL−1. Therefore, according to the present study, PCT concentration seems not to be particularly useful for the detection of lower respiratory tract infections e.g. CRP. Similar results were obtained by Hedlund and Hansson 21, who compared CRP and PCT levels in CAP in adults. However, Moulin etal. 22 described a superiority of PCT over CRP concentration in paediatric patients with CAP. In the recent publication of Brunkhorst et al. 23, different results, with elevated PCT levels in patients with severe pneumonia, were demonstrated. In contrast to the present study, the latter study included only patients with severe pneumonia, who were treated in the intensive care unit. This could also be a reason for the elevated PCT levels. Although diagnostic value has not been proved, PCT ...

We have cloned and characterized a second form of the human calcitonin receptor from T47D cells. It resembles the clone described by Gorn et al. [J. Clin. Invest. 90:1726-1735 (1992)] except that it lacks a 16-amino acid insert in the putative first intracellular loop. The insert-negative receptor appears to be the most abundant form, and it occurs at a relatively constant level in all expressing tissues. In contrast, the insert-positive receptor is found at low levels in most tissues but its expression levels appear to be much more variable. The insert-negative cDNA was stably expressed in baby hamster kidney cells. Like the endogenous T47D receptor, the recombinant receptor has an equally high affinity for salmon and porcine calcitonin but a 3-4-fold lower affinity for human calcitonin. High concentrations of calcitonin gene-related peptide, rat amylin, secretin, or vasoactive intestinal peptide do not significantly compete with calcitonin for binding to the recombinant receptor. Calcitonin ...

Definition of Procalcitonin in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is Procalcitonin? Meaning of Procalcitonin as a legal term. What does Procalcitonin mean in law?

FRMC Pharmacy Director, Mike Broyles PharmD, has worked diligently for the past several years, crossing the country, educating Healthcare Representatives about Antibiotic Usage and improving patient outcomes. He recently completed a study in which he included data from over 2100 patients that had been treated at Five Rivers Medical Center. The study consisted of comparing data that was found with the patients who were treated with antibiotics prior to the use of a laboratory test called Procalcitonin (PCT) and those that were treated after the test was available. Procalcitonin (PCT) is a Peptide Precursor of the hormone Calcitonin. The level of Procalcitonin will rise in the presence of a bacterial infection. During the course of antibiotic treatment for these bacterial infections, PCT is measured to verify that the antibiotic administered is decreasing the level of PCT found circulating in the patients bloodstream. If not, Antibiotics might need to be adjusted or changed. As PCT decreases, the ...

TY - JOUR. T1 - Prostaglandin E2 enhances bradykinin-stimulated release of neuropeptides from rat sensory neurons in culture. AU - Vasko, M. R.. AU - Campbell, W. B.. AU - Waite, K. J.. PY - 1994/8/1. Y1 - 1994/8/1. N2 - Prostaglandins are known to enhance the inflammatory and nociceptive actions of other chemical mediators of inflammation such as bradykinin. One possible mechanism for this sensitizing action is that prostanoids augment the release of neuroactive substances from sensory neurons. To initially test this hypothesis, we examined whether selected prostaglandins could enhance the resting or bradykinin-evoked release of immunoreactive substance P (iSP) and/or immunoreactive calcitonin gene-related peptide (iCGRP) from sensory neurons in culture. Bradykinin alone causes a concentration-dependent increase in the release of iSP and iCGRP from isolated sensory neurons, and this action is abolished in the absence of extracellular calcium. Pretreating the neurons with PGE2 (10 nM to 1 μM) ...

High concentrations of calcitonin may be able to increase urinary excretion of calcium and phosphate via the renal tubules.[9] leading to marked hypocalcemia. However, this is a minor effect with no physiological significance in humans. It is also a short-lived effect because the kidneys become resistant to calcitonin, as demonstrated by the kidneys unaffected excretion of calcium in patients with thyroid tumors that secrete excessive calcitonin.[10] In its skeleton-preserving actions, calcitonin protects against calcium loss from skeleton during periods of calcium mobilization, such as pregnancy and, especially, lactation. The protective mechanisms include the direct inhibition of bone resorption and the indirect effect through the inhibition of the release of prolactin from the pituitary gland. The reason provided is that prolactin induces the release of PTH related peptide which enhances bone resorption, but is still under investigation.,[11][12][13] Other effects are in preventing ...

BACKGROUND: In February, 2017, the US Food and Drug Administration approved the blood infection marker procalcitonin for guiding antibiotic therapy in patients with acute respiratory infections. This meta-analysis of patient data from 26 randomised controlled trials was designed to assess safety of procalcitonin-guided treatment in patients with acute respiratory infections from different clinical settings. METHODS: Based on a prespecified Cochrane protocol, we did a systematic literature search on the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase, and pooled individual patient data from trials in which patients with respiratory infections were randomly assigned to receive antibiotics based on procalcitonin concentrations (procalcitonin-guided group) or control ...

BACKGROUND: Procalcitonin is useful for the diagnosis of sepsis but its prognostic value regarding mortality is unclear. This prospective observational study was designed to study the prognostic value of procalcitonin in prediction of 28 day mortality in patients of sepsis. Fifty-four consecutive patients of sepsis, severe sepsis and septic shock defined using the 2001 Consensus Conference SCCM/ESICM/ACCP/ATS/SIS criteria from medical Intensive Care Unit (ICU) of a tertiary care center in New Delhi, India were enrolled from July 2011 to June 2013. Procalcitonin (PCT), C-reactive protein (CRP) measurements were recorded on day 1, day 7 and day 28 of follow up ...

Calcitonin-secreting neuroendocrine neoplasms of the lung are rare, with few cases reported in the literature. Differentiating between medullary thyroid carcinoma and an ectopic source of calcitonin secretion can represent a complex diagnostic conundrum for managing physicians, with cases of unnecessary thyroidectomy reported in the literature. This manuscript reports a case of ectopic hypercalcitonaemia from a metastatic neuroendocrine neoplasm of the lung with concurrent thyroid pathology and summarises the results of a systematic review of the literature. Medical Literature Analysis and Retrieval System Online, Excerpta Medica, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and SCOPUS databases were systematically and critically appraised for all peer reviewed manuscripts that suitably fulfilled the inclusion criteria established a priori. The protocol for this systematic review was developed according to the Preferred Reporting Items for Systematic review and ...

Pierre Hausfater and Bruno Riou. We thank van Oers and colleagues for their comments. We agree that likelihood ratios (LR) are useful tests in interpretation of clinical findings, laboratory tests, and image studies, although they are little used [3]. However, we do not think that LR is the unique response to a complex issue. First, LR is provided for a given predetermined threshold and we are convinced that the threshold of procalcitonin (PCT) highly depends on the population tested and the type of infection studied. Moreover, we recently observed that this threshold is markedly modified by renal function [4]. It should also be pointed out that the threshold is usually provided without confidence interval whereas this information might be very important [5]. In contrast, the receiver operating curve (ROC) provides a global assessment of diagnostic accuracy without any focus on a given threshold. Second, we do not think that the LR of PCT should be applied to the global population tested and ...

Lysine vasopressin (antidiuretic hormone), like cyclic adenosine 3,5-monophosphate (cyclic AMP), rapidly (in less than 1 hour) stimulates the initiation of deoxyribonucleic acid synthesis and thereby increases the flow of cells into mitosis in rat thymic lymphocyte populations in vitro. This mitogenic action of vasopressin, again like that of cyclic AMP, is potentiated by caffeine, an inhibitor of the intracellular phosphodiesterase which catalyzes the degradation of cyclic AMP. On the other hand, vasopressins mitogenic action (also like that of cyclic AMP) is blocked by imidazole, an activator of cyclic nucleotide phosphodiesterase activity. The hormone, thyrocalcitonin (calcitonin) which is known to block the cyclic AMP-mediated mitogenic effect of parathyroid hormone by interfering with cyclic AMP action, also blocks the mitogenic action of vasopressin. The inhibitory effects of imidazole and thyrocalcitonin on vasopressins mitogenic action are both overcome by the phosphodiesterase inhibitor

A summary of the article is shown below:. BACKGROUND: There is only limited information on serum reference ranges of calcitonin (CT) in infants, children and adolescents. This gap hampers valid diagnostics in patients with multiple endocrine neoplasia type 2 (MEN 2) and planned prophylactic thyroidectomy. In addition, age-dependent reference ranges for CT are necessary to define a cure in medullary thyroid carcinoma (MTC). We asked whether the reference ranges for CT levels were age- and gender-dependent in the serum of a pediatric cohort.METHODS: A total of 6090 serum samples of 2639 subjects of the LIFE-Child cohort aged between 1 month and 17.9 years were analyzed by the CT electrochemiluminescence immunoassay (ECLIA). Reference intervals were estimated using the LMS method. For clinical validation the serum of 28 patients (61 samples) with MEN 2 and 106 patients (136 samples) with thyroid diseases were analyzed.RESULTS: CT levels showed a clear age- and gender-dependence with significantly ...

Both calcitonin and prostaglandin E2 (PGE2) stimulate adenylate cyclase activity in the human breast cancer cell line (T 47D). The maximum cyclic AMP response to calcitonin exceeds that of PGE2. When maximal concentrations of the two hormones were added simultaneously to the cells, the amount of cyclic AMP generated was less than that seen with calcitonin alone. When cells were treated with the protein toxin of Bordetella pertussis (islet-activating protein; IAP) which inactivates the inhibitory regulatory component (Ni) of adenylate cyclase, there was no change in basal or calcitonin-responsive adenylate cyclase in intact cells. However, the PGE2 response was augmented at all dose levels, and this effect was dependent on the concentration of IAP. Moreover, in cells pretreated with IAP, simultaneous addition of PGE2 and calcitonin resulted in additivity rather than in inhibition of cyclic AMP production. The additivity of the response to calcitonin and PGE2 after IAP treatment implies activation ...

Calcimimetic compounds, which activate the parathyroid cell Ca2+ receptor (CaR) and inhibit parathyroid hormone (PTH) secretion, are under experimental study as a treatment for hyperparathyroidism. This report describes the salient pharmacodynamic properties, using several test systems, of a new calcimimetic compound, cinacalcet HCl. Cinacalcet HCl increased the concentration of cytoplasmic Ca2+ ([Ca2+]i) in human embryonic kidney 293 cells expressing the human parathyroid CaR. Cinacalcet HCl (EC50 = 51 nM) in the presence of 0.5 mM extracellular Ca2+ elicited increases in [Ca2+]i in a dose- and calcium-dependent manner. Similarly, in the presence of 0.5 mM extracellular Ca2+, cinacalcet HCl (IC50 = 28 nM) produced a concentration-dependent decrease in PTH secretion from cultured bovine parathyroid cells. Using rat medullary thyroid carcinoma 6-23 cells expressing the CaR, cinacalcet HCl (EC50 = 34 nM) produced a concentration-dependent increase in calcitonin secretion. In vivo studies in rats ...

Abstract: The goal of this study was to investigate the role of procalcitonin (PCT) in diagnosis of neonatal sepsis and its correlation with C-Reactive Protein (CRP). One hundred and seventeen neonates with the gestational age ≥35 weeks with clinically suspected diagnosis of neonatal sepsis were studied during one year from 2007 in Tabriz Children`s Hospital. Conventional sepsis workup was done in all cases and the diagnosis of neonatal sepsis was proved based on the results of blood culture. The serum procalcitonin was measured by quantitative Chemo-luminance methods and the results were compared with CRP levels between the neonates with and without proven sepsis. The results showed among in 117 neonates with suspected sepsis 27 (23.1%) cases have positive blood culture (proven sepsis). The mean levels of PCT in neonates with and without proven sepsis was 4.42 ±6.66 vs. 2.06 ±4.03 ng mL-1 and CRP 33.98 ±36.81 vs. 12.30 ±20.42 mg L-1 were significantly higher in neonates with proven sepsis ...

Calcitonin (salmon) is a 32-amino acid polypeptide hormone that is produced in humans primarily by the parafollicular cells (also known as C-cells) of the thyroid, and in many other animals in the ultimobranchial body. It acts to reduce blood calcium (Ca2+), opposing the effects of parathyroid hormone (PTH). The calcitonin receptor has been cloned and shown to be a member of the seven-transmembrane, G protein-coupled receptor family.

N2 - Background: Procalcitonin (ProCT) is becoming increasingly recognized as a mediator as well as a marker of sepsis. Serum ProCT concentrations rise soon after induction of sepsis and remain elevated over a prolonged period of time. In contrast, many pro-inflammatory cytokines, e.g., tumor necrosis factor alpha (TNF-α) and interleukin-1 beta (IL-1β), rise and decline early in the course of sepsis. Researchers have improved survival in animal models of sepsis by prophylactically blocking IL-1β and TNF-α with immunotherapy, but therapeutic treatment has been less successful in clinical trials. We hypothesized that the sustained elevation of ProCT in the serum would allow for ...

Objectives: Higher coronary atherosclerotic burden has been associated with increased cardiovascular events including mortality. The SYNTAX score (SXs) reflects coronary atherosclerotic burden. Given the body of evidence implicating inflammation in atherosclerotic process, we hypothesized that procalcitonin (PCT) as an inflammatory marker may be related to coronary atherosclerotic burden. Thus, we aimed to investigate the relationship between serum PCT levels and SXs in patients with stable CAD. ...

Several controlled clinical studies have evaluated the potential of the infection biomarker procalcitonin (PCT) to improve the diagnostic work-up of patients with bacterial infections and its influence on decisions regarding antibiotic therapy. Most research has focused on lower respiratory tract infections and critically ill sepsis patients. A clinical utility for PCT has also been found for patients with urinary tract infections, postoperative infections, meningitis, and patients with acute heart failure with possible superinfection (i.e., pneumonia). In these indications, PCT levels measured on hospital admission were found to substantially reduce the initiation of antibiotic treatment in low-risk situations (i.e., bronchitis, chronic obstructive pulmonary disease exacerbation). For more severe infections (i.e., pneumonia, sepsis), antibiotic stewardship by monitoring of PCT kinetics resulted in shorter antibiotic treatment durations with early cessation of therapy. Importantly, these strategies

Compared to those with bacterial or mixed infection (n = 9), patients with 2009 H1N1 infection (n = 16) were significantly more likely to have bilateral chest X-ray infiltrates, lower APACHE scores, more prolonged lengths of stay in ICU and lower white cell count, procalcitonin and CRP levels. Using a cutoff of ,0.8 ng/ml, the sensitivity and specificity of procalcitonin for detection of patients with bacterial/mixed infection were 100 and 62%, respectively. A CRP cutoff of ,200 mg/l best identified patients with bacterial/mixed infection (sensitivity 100%, specificity 87.5%). In combination, procalcitonin levels ,0.8 ng/ml and CRP ,200 mg/l had optimal sensitivity (100%), specificity (94%), negative predictive value (100%) and positive predictive value (90%). Receiver-operating characteristic curve analysis suggested the diagnostic accuracy of procalcitonin may be inferior to CRP in this setting.. ...

After birth the PCT values of the newborn increase over the first 24 hours and stay elevated during the first 2-3 days of life. Therefore separate, well-defined reference ranges apply to new born infants at different hours of age during the first 48 hours of life (see Figure below). However, also during these first days of life, the PCT values of newborns suffering from early sepsis are significantly higher than those of non-infected newborns, so that PCT can be used for sepsis diagnosis. The adult reference range applies after day 3.. ...
